Voronoi and surfaces

Guys, i need to help

I need to create a voronoi mesh or pattern on this pink surface or like this.
In fact I need to make a smooth surface like this pink structure (like one if it were a hollow shell) and apply voronoi on it. Anyone have an idea how to go?

The file are here

Surface.gh (22.9 KB)
Surface1.3dm (107.4 KB)

Hope it helps out.
